The poll I'd like to see is between Blanco, Jindal and Lt. Gov. Mitch Landrieu (Senator Mary's brother). If Jindal is below 50% and Landrieu finishes 2nd, that would make me think that Mitch Landrieu will run for governor and hope for a run-off spot, which has worked lika a charm for RATs during the past 10 years or so; the only Republicans to win statewide during the past decade have been Governor Foster and Senator Vitter, each of whom managed to avoid a December run-off (Foster was first elected in 1995 in a run-off, but it was against black ultraliberal Cleo Fields and I don't think we'll ever get that lucky again).
Congressman Jindal needs to declare his gubernatorial candidacy as soon as practicable so that no other Republicans run. He needs to get over 50% in November of 2007.
Jindal will declare after his election victory to the House in October (barring, of course, no runoff).
